1N3289AR

Single Diodes Overview

The 1N3289AR is a high-current silicon rectifier diode manufactured by Powerex Inc. It features a maximum average forward current of 100 A and a repetitive peak reverse voltage rating of 200 V. The device utilizes a stud-mount configuration with the cathode connected to the stud, indicated by the 'R' suffix in the part number. It is housed in a DO-8 package and is designed for robust power conversion applications requiring high surge current handling capabilities.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific manufacturer source, as historical data links this series to Transys Electronics Limited. Confirm that the 'R' suffix correctly denotes the cathode-to-stud configuration required for your mounting scheme. Ensure the DO-8 package dimensions match your mechanical constraints before procurement.

Single Diodes Selection Notes

Select this component when a 100 A average current rating and 200 V blocking voltage are required. The stud-mount design is optimal for applications needing direct heatsink attachment. Consider the forward voltage drop characteristics for thermal calculations in high-load scenarios.

Single Diodes Part Context

This part belongs to the 1N3288 through 1N3297 series of high-current rectifiers. These devices share a common 100 A current rating but vary in reverse voltage ratings from 50 V to 1400 V. The 1N3289AR specifically provides the 200 V option within this standardized family.

Single Diodes Replacement Considerations

Direct substitutes include other 1N3289 variants or equivalent 100 A, 200 V stud-mount diodes from manufacturers like Littelfuse or Vishay. Verify pinout compatibility, specifically the cathode-to-stud orientation, and ensure thermal resistance values meet system requirements.
